If the police took bodily fluids from you during the arrest then those bodily fluids can be tested for drugs and alcohol. An intoxicating substance includes any drug, alcohol, dangerous drug, or a controlled substance that makes it so you do not have the normal use of your intellectual or physical faculties. It is, usually, more difficult to say that someone is under the influence of marijuana than it is to say they are under the influence of marijuana. Still, it depends on the philosophy of the county where you were arrested and the expertise of the officer who arrested you. If you were not arrested but a blood sample was taken, it is likely that a warrant for your arrest will be issued once the blood is tested. Hiring a lawyer will allow you to keep track of where the case is and allow you avoid any nasty surprises.

A DUI, no. A DWI, yes. Such a case can be difficult to prove based on drugs alone, and usually depends on just how badly you were driving. A DUI is basically restricted to someone under 21 who had consumed any detectable amount of alcohol and was driving. A DWI is the more common offense, can be based on either alcohol or drugs, and requires proof that you were not in the same mental or physical condition that you normally are and that affected your ability to drive.
